plot_spectra: Plot spectra

Description

Plot spectra from dataset.

Usage

plot_spectra(dataset, column.class, func = NULL, samples = NULL, 
variable.bounds = NULL, xlab = NULL, ylab = NULL, lty = 1, 
legend.place = "topright", cex = 0.8, reverse.x = F, ...)

Arguments

dataset

list representing the dataset from a metabolomics experiment.

column.class

string indicating the metadata's variable.

func

function to compute the summary statistics to apply to the data.

samples

vector with samples' names, if NULL all the samples will be considered.

variable.bounds

numeric vector with two elements indicating the interval of x-values to plot.

xlab

x-axis label.

ylab

y-axis label.

lty

parameter of matplot.

legend.place

string indicating the place that the legend's box will be placed.

cex

numeric value that indicates the amount by which the legend is magnified relative to the default.

reverse.x

boolean value indicating if the x-axis will be shown reversed or not.

…

additional parameters to matplot.
